Classical taxonomic measurements represented by the mean and standard deviation, except for species represented by fewer than 3 specimens, where only the mean is calculated. Total length (TL), Head length (HDL), Fork length (FL), Precaudal-fin length (PCL), Predorsal-fin length (PD), Prepectoral-fin length (PP1), Prepelvic-fin length (PP2), Preanal-fin length (PAL), Body depth (BD), Head length (HDL), Preorbital length (POB), Eye diameter (ED).
